用来判断样本是否线性可分的 用来判断样本是否线性可分的 (ll)

通过此卡尔曼滤波，可获得比较精准的载体位置，速度，加速度等信息。(Through the kalman filter, can get a more accurate carrier position, velocity, acceleration and other information.)

matlab code with examples

此代码是利用 MATLAB 工具设计的一个指纹数字图像识别系统的关键代码(fingerprint identification)

main executing reference usage: usage_timeDifference.m Sample output: The time interval between earierTime [09-Sep-1900 09:09:18] and laterTime [31-Oct-2010 23:33:08] is 110 years, 79 days, 14 hours, 23 mins, 50.17 secs. The objective is to compute the time interval taking into account the leap days that are subsumed within the time interval. Note: The logic subsumes the time interval by yearEnd, monthEnd, dayEnd - timeEarlier (within that year) + time interval (excluding that 2 years) + timeLater - yearEnd, monthEnd, dayEnd (within that year) It differentiates the earlier time and later time, ie. timeDifference (earlierTime, laterTime) gives the same result as timeDifference (laterTime, earlierTime). leapDayHasPassed.m illustrates a possible approach to determine if a certain day of concern is already over at a given time. Caveat: does not include leap secs
